AI subtitles for streaming video — in sync, cached free on replay, or hear it translated aloud live in your language. Watch any video in your language. SubVibe adds AI subtitles to a video and keeps them perfectly timed to the player, with a karaoke highlight that lights up each word as it's spoken — and it can speak the translation aloud, in real time, while you watch.
Bring your own API key (OpenAI, Anthropic, or Google). Everything runs directly from your browser to the provider you choose — no SubVibe servers, no account, no tracking. Translated videos are cached on your device, so replays are free.

Where it works
SubVibe runs right inside the player on the streaming services, public broadcasters, and online-course sites it supports, with more on the way. On every other page it stays completely inactive.
